It is not right, in papers, to put the animals in alphabetic sequence jpistead of systematic relations. And then one cha^iges its name as in the Chromodorididae frequently, and appears in quite another place in the next paper. I am sorry that Ti^ Veliger ailows that, but they have done that for a long time." From Susan H. Wells, Co-compiler, Invertebrate Red Data Book, International Union for Conservation of T'^ature and Natural Resources, Species Conservation Monitoring Unit, 219(c) Huntingdon Road, Cambridge, C33 ODL, U.K.: "I obtained your name and address from the Opistho'o ranch ^wslBtter and am writing to enquire wliether you or any of your contacts could help us. I am currently working on the compilation of the first volume of the lUCN Red Data Book for Invertebrates with special responsibility for non-insect groups. Foilovjlng its publication I hope to be working on a more specialised volume for molluscs. Initially I had not expected to find any information on threatened opisthobranchs. However, a contact in the Netherlands provided information on an endangered nudlbranch and I enclose a copy of the data sheet. 1 would be 'r.t9rs5'-/id to know if you or any of your colleagues have information on species in similar situations, and whether your newsletter could be used for advertising our need for ZUIDERZEE NliPIBRANCH Corambe batava Kerbet, 1&S6 Phylum HOLLUSCA NUDIBRANCHIA Class GASTROPCDA CORAf-iBIDAE ENDANGERED Orde*f Family SUi^SiARI This small brackish water sea slug is endemic to an area centred on the former Zuiderzee in the Netherlands. The closure of the Zuiderzee caused its disappearance from most known localities, including its type locality, and it may now be extinct. DESCRIPTION Tne shape of the mantle which is complete at the posterior end of the animal separates this species from its nearest relative, C. sargassicola from the Sargasso Sea (1). A small sea slug reaching only about 5mm in length, C. batava is variable in colour, ranging from yellow with black patches to dark brown or black all over. It has a circular • disc-shaped mantle and a flat, almost circu.lar foot (4). DISTRIBUTION Endemic to Holland. The type locality is at Durgerdam near Amsterdam beyond the River I.j. It has been recoraed from tne coasts of the former Zuiderzee from Amsterdam to Den Helder in many localities (1), including Wieringen on the Vangdam and near Oudeschild in Texel (3,4). ' POPULATIOM Unknovffli. HflBITAT AND ECOLOGY Found in brackish water generally in salinities from 7-25»o, but it can probably withstand salinities up to 30|o since large numbers have oeen round in Den Helder harbour. The lowest salinity in which it has been found is 6.7$o. It is restricted to shallow water on or near Cordylophora caspia on which it may feed; it has also been found on Meaibranipora (1,2). SCIEN'TIFIC INTEREST Am POTENTIAL VALUE THREATS TO SURVIVAL The closing of the Zuiderzee resulted In the disappearance of all tne brackish water fauna in tne area, and C. batava is almost certainly now extinct and definitely extinct in its type locality (1). The Zuiderzee was closed in May 1932, following which this species continued to be found in the northern part of the enclooed area uatil July of that year since when it has not been found there. In 1947 it was recorded at Texel (2). OPISTEOBAKCH NEWSLETTER CONSERVATION MEASURES TAKEN None. CONSERVATION MEASURES PROPOSED It could possibly still survive, in the harbour at Den Haider or in brackish water on some of tne Wadden Sea Islands, such as Texel. However both these areas are severely polluted. It is also conceivable that the species may be foOnd in France or England (5). Surveys should be carried out in the 'Wadden Sea and Den Helder harbour to ascertain if this species is still extant. If it is found, steps should be taken to ensure that it is protected in a suitable unpolluted area of brackish water. REFERENCES 1. BUTOT, L.J.M. (1977).

My trip was nice as always, beginning with Terrence Gosliner in Cape Town, where we had long conversations about Pleurobranchaeidae, and finished a review of the family. Then I was with Claude Poizat, later I met Luise Schmekel, in between, family and friends, and stayed in Washington and with Dr. Rosalie Vogel, married Curabee. Now I will begin a revision of the Pie uro bran chidae, but it will take some time; I am getting old and work does not go as fast as when I was younger." From James Lance: "During Spring/Summer, 19b2, we organized a number of overland and air expeditions to Bahia de ios Angeles, Sea of Cortez, Mexico, for the purpose of making a comprehensive survey of inter- and subtidai opisthobranch fauia during a given season. 1 hoped that these data, when combined with \?oi. 14(9):31. previous information gathered over the past 25 years, would provide a general picture of the opisthobranch populations from this area. Our overall task force of active collectors/ observers was not small (28 people participated). But it must be admitted that only 7 of these could be described'as experienced 'branch collectors. Still, over 500 SCUBA and 200 intertidal man hours (pardcn me, person hours) were logged during tnis operation. Ihe area collected was sLmply uhe greater Bahia de los Angeles - its myriad rocky island shores and the channels between. For the most part, weather was perfect with glassy seas and clear visibility. Our entire operation came up with a rather disappointing 48 species - 40 of which we collected during 5 days in Kiay during extreme low, dawn tides in the Lntertidal; especially around the rocky islands. Some findings, however, should be enough to intrigue the biologically oriented opisthobranchologist: 1. For the first time in the eastern Pacific we have found a cryptobranch dorid parasitized by an internal copepod aj^te different from literature reports. 2. California's Flabellinopsis iodinea is our most colorful aeolid. This survey provided a startling look-alike not e'/en in the same family. 3- A new aeolid that appears to feed exclusively en a sjraibiotic hydroid grC'jing on the back (dorsum) of a small, under-rock inhabiting prosobranch was found. A similar case has been reported from the northwestern Atlantic. 4. Tasbja adere vs. Tanibja fusca: separate or the same species? Ever since Farmer (197b) described this (these) animals from the northern Panamic the validity of two species has been questioned. On. theses trips we were able to obtain more than a hundred specimens and study them in life. I would expect the results of this inquiry to satisfy most taxonomists. None of this work could have been carried out without the help of expecially dedicated persons. In particular I thank Connie Boone, Brad Carte and Johji 'Sullivan for their contributions. — Jim Lance. Dave Behrens is working on two new Corypheila spp. From Terry Gosliner: "First of all, I wanted to tell you that I will be in your area on a permanent basis. I just returned from a quick trip to San Francisco and will begin work at the Cal Academy on Dec. 1 as the new curator of moxlusks. Needless to say I am very pleased. In March I will be at the Smithsonian for a year and then return to San Francisco permanently. The Dock will be about 150-17" caies, I suspect and will contain at^ont :3r plates of all the species discussea. .ni^.D ■c, owo-thirds of the species nave not previously been recorded from southern Africa previously so it Yol. 14(9 ):32. OPISTHOBKANCH NF^SLETTER represents a significant increase in the knowledge of the fauna. Also included is a forev;ard by T.E. Thompson, an introduction discussing the. evolutionary history, defense mechanisms, feeding, reproduction and larval biology of opisthobranchs. This is followed by sections on the systematics and collection of opisthobranchs and their biogeography in southern Africa. There is also a chapter en how to classify opisthobranchs designed for the layman but describes why internal morphology is essential. This section includes a glossary illustrated with numerous pen and ink drawings and a key to the identification of living specimens of all the species discussed. 1 tnink the price is fair. The format and size will be the same as the brochure I sent. It will be printed on high gloss paper, like the brochure, which pushes the cost up, but also the quality. It will only be printed in hard back, as Vve.U, at- this time." Nudibranchs of Southern Africa by Terrence Gosllner will be available from the Opisthobrancfa Ifewsletter for $30.00 U.S. plus postage and applicable taxes. Jim hcLean spent a week back in Cape Cod, Massachuset.ts this summer. From Dr. I.S. Roginskaya: "I am sending you an article of Soviet malacologist Dr. K.N. Nesis, concerning the interrelations of Aeolidia papillosa and sea-anemone Anthopieura elegantissisa, published In our popular m.agazine Science and Life. Aeolidia papillosa was photographed by me at the White Sea Biological Station. Wes Farmer, 410 So. 1st St. Sp.ld2, El Cajcn, CA 92021 (7l4)5c5b-ai53, is still making Opisthobranch models. If you are interested in one of his beautiful models, please contact him. Dave Behrens has recently taken some time off from branching to publish a short paper on the mating behavior of the Gray Whale, Eschrictius robustus. His paper just appeared in Califoraia Fish and Gane, 6o(1):50-53 + photos. . In late June, Steve Long, Roberta Relihard, Dave Mulliner, Peg Muliiner, and Joan Steinberg all. spent the afternoon at Jim Lance's. It was good to meet Dr. Steinberg after all these years. On October 15, 19b2, Pete Oringer, Howie Katzman, Steve Long, and Roberta got together for dinner in Long Beach. Pete is dowri from Eureka, California on business. From ^Selissa Barbour: "Just about the time your notice came we were In the throes of big changes. Jim started to work for the State Water Resources Control Board In Sacramento. He has been commuting 2X/weeK since then. I returned to work after a 3 mos. maternity leave, vte had a little girl, Nora, In January. I-jow we will be moving to Sacramento In the next month. I finished golig through the MacFarland slides, etc. just before Nora was bom — they have been collated Into the collection at California Academy of Sciences — some into the type collection and some into the regular collection. They are now at least flndable. That will probably be ray last Opisthobranch work for a while- Nora takes a lot of time & energy at this time." -- Melissa A. Barbour From Ian Loch: "li March, EUl Rudman, Geoff Avem, Judith Hunter, Helen Woodward and myself spent four days collecting around Yamba in northern N.S.W. Strong winds and a big swell reduced Geoff and I to 'diving' In tide pools, but the overall collections were quite good, about bO species. Diving in tide pools does concentrate the effort. Some of the beasts found were, Favorinus japa:iiGus In a variety of colour forms, Spurilla alba, S. australis, Phidiana bourailli, a new Phiaiana with oright blue bands on its cerata, Favorinus tsurugensis, a Limenandra, ^oJJ-diella takanosinjensis, a tritcniia en Telesto, a tiny Ckadaia, ^gires citrina, Geo iodc ride 11a savignyi; Plocaaioperus ceylanicus, Okenia pellucida and another Ckenia en Zoobotryoo, Miamira flavicostata, Ctenodoris pecten; Dendrodoris gemmacea, D. guttata and otners Indeterminate as usual, a range of Pleurobranchus and various flat dorids including a common Discodoris which we found can 'control' its colour from light to dark." PatricK LaFoilette was been working at the AAAS in Washington, D.C., during August, and is now (October) on vacation In Canada. He stopped to see Sandra Fallen in Vancouver on the way up.
